found to be an excellent ligand for copper-catalyzed N-arylation of azoles and amides with aryl halides under mild conditions. The reaction took place at 82 °C in MeCN with broad functional-group compatibility. A combination of the ligand and CuI proved to be an efficient catalytic system to promote the coupling reactions of aryl halides with azoles and amides.

Weakly basic amines, including even neutral amines such as nitroaniline and aminocarboxylic acids, react with acid chlorides very efficiently in N,N-dimethylacetamide (DMAC), without addition of a base, to give the corresponding amides in high yields. The role of DMAC and related solvents as latent Brønsted bases was studied in these amidation reactions. Less basic amines, such as aromatic amines, reacted

The occurrence of 3D isostructurality in six halogensubstituted N-benzoyl-N-phenylbenzamides has been reported and this feature has been quantitatively analyzed in this study. 4-fluoro-N-(4-fluorobenzoyl) N-(fluorphenyl)benzamide (1) was observed to be isostructural with 2-fluoro-N-(2fluorobenzoyl) N-(4-fluorophenyl)benzamide (7), N-(4-bromophenyI)-2-fluoro-N-(2-fluorobenzoyl) benzamide (8) and 2
